Design and study of two axis tracking system

Abstract

In this paper we presents the design, construction and also investigates the experimental study of a two axis (azimuthally and Polar) automatic control solar tracking system to track solar dish according to the direction of beam propagation of solar radiation. The designed tracking system consists of sensor and controller with built operated control circuits to drive motor with control .The designed Sun tracker was operated in the control system, two steeper motors were used to the movement of the system, keeping the sun’s beam at the center of the sensor. To investigate the effect of using two-axis sun tracking systems.The measured variables were compared with the fixed axis, the results indicate that the energy surplus becomes about (20-30%) with atmospheric influences. In case of seasonal, The system is a flexible tracking system with low cost electromechanical set-up, low maintenance requirements and ease of installation and operation.
